Sarah Thompson, an American visiting England, meets and marries William Whitfield, the Duke of Whitfield. They settle in a chateau in France and begin a family. World War II interrupts their happiness and alters their future. After the war, the family helps war survivors by buying their jewelry and eventually opens a jewelry store, which rapidly becomes a success. But conflicts abound as new generations arise and forces from both outside and within threaten the store and the family.
